Water
The baseline drink of life, and the Bible's chief metaphor for cleansing and renewal.
Scripture
14 Abraham rose up early in the morning, and took bread and a bottle of water, and gave it to Hagar, putting it on her shoulder; and gave her the child, and sent her away. She departed, and wandered in the wilderness of Beersheba.
14 but whoever drinks of the water that I will give him will never thirst again; but the water that I will give him will become in him a well of water springing up to eternal life."
42 Whoever gives one of these little ones just a cup of cold water to drink in the name of a disciple, most certainly I tell you he will in no way lose his reward."
